Description

Technical Field

[0001] This utility model relates to the field of refractory brick technology, and in particular to an anchoring type refractory brick for industrial kilns. Background Technology

[0002] In industrial kilns, insulation strips, flow channels, and other components require the installation of refractory bricks to achieve insulation, isolation, and erosion resistance. Typically, construction companies simply use mortar to sequentially lay the refractory bricks onto the kiln's outer iron sheet. However, after prolonged operation, especially after repeated cycles of thermal expansion and contraction, the refractory bricks can loosen or even detach from the kiln's iron sheet, significantly impacting the kiln's performance. Therefore, there is an urgent need for a type of refractory brick that can be more securely installed on the kiln's iron sheet to prevent easy detachment due to thermal expansion and contraction. Utility Model Content

[0003] The purpose of this utility model is to provide an anchoring type refractory brick for industrial kilns, so as to solve the problem that traditional refractory bricks will loosen and fall off after repeated expansion and contraction due to alternating hot and cold temperatures when laid with the iron sheet of the kiln, thus affecting the performance of the kiln.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An anchored refractory brick for industrial kilns includes a brick body and an anchor embedded in the brick body. The anchor has at least two welding angles, and at least one welding angle of the anchor is located on the outer bottom surface of the brick body, and the welding angle is flush with the bottom surface of the brick body.

[0006] A further technical solution is that the anchor has at least two symmetrically arranged positioning angles, the positioning angles are located on the top outer side of the brick, and the outer bottom of the brick is symmetrically provided with positioning grooves that are adapted to the positioning angles.

[0007] A further technical solution is to increase the outward spacing between the two symmetrical positioning angles.

[0008] A further technical solution is: a receiving groove adapted to the welding angle is provided on the side of the brick without the welding angle.

[0009] A further technical solution is that the two anchors are connected by a connecting rod.

[0010] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0011] This utility model proposes an anchored refractory brick for industrial kilns. The refractory brick can be welded to the kiln sheet by means of welding feet with embedded internal anchors. This connection method is not affected by general thermal expansion and contraction, so the refractory brick will not easily loosen or fall off the kiln sheet. Moreover, this connection method reduces the use of mortar, greatly reduces the waiting time caused by mortar solidification, and improves efficiency. Attached Figure Description

[0024] Example 1:

[0025] This implementation example Figure 1 As shown, an anchored refractory brick for industrial kilns includes a brick body 1 and an anchor 2 embedded in the brick body 1. The anchor 2 has at least two welding angles 3, and at least one welding angle 3 of the anchor 2 is located on the outer side of the bottom of the brick body 1, and the welding angle 3 is flush with the bottom surface of the brick body 1.

[0026] First, at least one welding foot 3 of the anchor 2 extending out of the brick body 1 is welded to the kiln sheet. Then, starting from the first refractory brick, the remaining refractory bricks are welded in sequence. This connection method is not affected by the general phenomenon of thermal expansion and contraction, so the refractory bricks will not easily loosen or fall off from the kiln sheet. Moreover, this connection method reduces the use of mortar, greatly reduces the waiting time caused by the mortar solidification, and improves efficiency.

[0027] Example 2:

[0028] Based on the above embodiments, this embodiment Figure 2 and Figure 3As shown, the anchor 2 has at least two symmetrically arranged positioning angles 4, the positioning angles 4 are located on the top outer side of the brick body 1, and the outer bottom of the brick body 1 is symmetrically provided with positioning grooves 5 that are adapted to the positioning angles 4.

[0029] When refractory bricks are stacked (not laid flat), two adjacent refractory bricks may be connected vertically. In this case, the positioning groove 5 of the upper refractory brick can be inserted into the positioning angle 4 on the anchor 2 of another refractory brick. This serves two purposes: first, to achieve positioning (pre-fixing); and second, to reinforce the refractory bricks together in subsequent use.

[0030] Preferably, the outward spacing between the two symmetrical positioning angles 4 is increased.

[0031] The positioning angle 4 is tilted outward to facilitate the mutual adaptation between the positioning groove 5 and the positioning angle 4.

[0032] Example 3:

[0033] Based on the above embodiments, this embodiment Figure 3 and Figure 4 As shown, a receiving groove 6 adapted to the welding angle 3 is provided on the side of the brick body 1 without welding angle 3.

[0034] When two refractory bricks are laid flat, that is, when they are adjacent to each other, the welded foot 3 on one refractory brick that is exposed can be extended into the receiving groove 6 of the other refractory brick. This serves two purposes: first, to position (pre-fix) the bricks, and second, to reinforce each other during subsequent use.

[0035] Preferably, such as Figure 5 As shown, the two anchors 2 are connected by a connecting rod 7.

[0036] There are two anchors 2, which can be distributed along the length of the brick 1 to share the external force on the brick and improve the strength of the brick 1. In addition, they can also evenly distribute the welding feet to ensure that the refractory brick is subjected to uniform force.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
